The formation of the novel hydrocarbons, tetracyclo[7.2.1.02,5.02,8]dodecadienes, as a result of thermal isomerization of spiro[2.4]hepta-4,6-diene into bicyclo[3.2.0]hepta-1,3-diene and its capture by 1,3-dienes is demonstrated. The conditions of thermal isomerization and dimerization of the spiroheptadiene are studied. Cyclopropanation of the polycyclic dienes formed by diazomethane in the presence
由于螺[2.4]庚-4,6-二烯热异构化为双环[3.2.0]庚-1,3-,形成新型烃四环[7.2.1.02,5.02,8]十二碳二烯演示了二烯及其被 1,3-二烯捕获。研究了螺庚二烯的热异构化和二聚化条件。在 Pd 催化剂存在下,由重氮甲烷形成的多环二烯的环丙烷化完成,并且仅通过降冰片烯双键发生。
